Imagine that you are walking on a path through a forest in the Adirondacks and suddenly, you see an opening in the trees ahead. Moving closer, you gaze out on a vast opening covered in a mosaic of leafy shrubs and dotted with spiky conifers. You take a step further and feel the “squish” as your boot sinks into a wet, dense mat of bright green moss. From the top of a nearby snag, you hear the distinctive “quick-three-beers” song of an Olive-sided Flycatcher followed by the complex, jumbled, slightly metallic sound of a Lincoln’s Sparrow. Looking down again, you notice the pale, delicate flowers of a white-fringed orchid. All the sights and sounds are conclusive: you have entered the Adirondack boreal.
The term “boreal” is used to describe cold, wet areas in northern latitudes. For the most part, people think of northern Canada and Eurasia, with vast spruce-fir forests, extensive wetland complexes, and frigid winter conditions. Though much of the Adirondack Park is within the temperate deciduous bioclimatic zone, we can also find low-elevation boreal pockets containing bog rosemary, pod-grass, tamarack and other boreal plants.
Lowland boreal wetlands, including conifer swamps and peatlands like bogs and fens, make up about one-third of all Adirondack wetlands and about 5% (250,000 acres) of the Park. Because they are still largely intact ecologically, provide habitat for rare plant and animal species, are found at the southern edge of the boreal forest, and are separated geographically from similar habitat in Canada, these wetlands represent important conservation targets in the Adirondacks.
Boreal birds depend on these specialized habitats for a variety of resources. For example, Gray Jays create nests in the boughs of conifer trees and use their sticky saliva to create caches of food in the trees. The Olive-sided Flycatcher prefers open woodland habitats and is often found in boreal bogs where dead trees provide excellent perches for “sallying” (flying out to snatch insects in midair). The Palm Warbler is almost completely dependent on peatlands, nesting in shrubby areas on top of Sphagnum moss mats. These species are obligate boreal species, meaning that they breed only where northern plant communities are present.
Some of the other bird species that specialize in boreal forested wetlands include the Yellow-bellied Flycatcher, Rusty Blackbird, Cape May Warbler, Blackpoll Warbler, Three-toed Woodpecker, and Spruce Grouse. Thirteen bird species (the Boreal Baker’s Dozen) represent this iconic lowland wetland community type in the Adirondacks.
Most boreal birds are not often seen or heard, even in ideal habitat. Some, like the Rusty Blackbird, have declined dramatically, while others seem to be chronically rare. Boreal wetlands are highly sensitive to environmental changes that reduce the amount or quality of boreal habitat. A variety of threats include climate change, habitat fragmentation and loss, and changes in the wetland hydrology (water movement and extent). Warmer temperatures in particular may cause boreal plant and animal ranges to shift north; in New York this has already been documented for bird species like the Rusty Blackbird. Increasingly small, isolated habitats support fewer and fewer birds. Mercury bioaccumulation in wetland songbirds is particularly severe. Finally, noise from roads and other human sources may disrupt the birds’ behavior. Though there is currently suitable habitat for boreal birds in Canada, wetlands there are under pressure from energy extraction and other threats.
A key information gap is determining where Adirondack boreal birds nest and feed. A new opportunity is coming for citizens who care about Adirondack wildlife and are interested in searching for the Boreal Baker’s Dozen. In spring 2014, a partnership of agencies and universities is starting a new volunteer monitoring project in the Adirondacks. The project is being funded by a United States Environmental Protection Agency grant administered by the Adirondack Park Agency. The goal is to study birds, plants, and amphibians in Adirondack wetlands and determine how climate change may affect them over time. Citizen scientists will visit boreal wetland sites to identify and measure rare wetland plants, count birds, and perform evening call surveys for amphibians.

I remember well the many hikes I made into and across the Bloomingdale Bog; the first, led by Adirondack Mt. Club naturalist Mark Gretch in the late 1980s, yielded many boreal bird species, ihncluding Gray Jay, Olive-sided Flycatcher, Yellow-bellied Flycatcher, and Palm Warbler.
Thank you for your comment! All four of the the bird species you mention are target species for the upcoming citizen science monitoring project. I invite you to attend the upcoming Wetland Detectives Training Workshops to learn more about these and other fascinating species:
I have not previously seen “boreal” used as a noun rather than an adjective, as in “boreal forest,” etc. Will participants have to be knowledgeable about plants, amphibians and birds in order to contribute?
Thank you for your feedback! No prior experience with wetlands or wetland species is required to participate in the upcoming Wetland Detectives Training Workshops. Project leaders will teach participants the skills needed to contribute to the monitoring effort.
We hope to see you there!
